Lenovo 1M OSFP800 to 4x QSFP56 DAC | 800G, Direct Attach

Consolidate high-speed interconnects without adding optical modules or extra patching layers. Lenovo’s 1 m OSFP800 to 4x QSFP56 DAC is built for short-reach breakout applications where signal integrity, port density, and cable discipline matter more than distance. It gives infrastructure teams a direct attach path from a single OSFP800 port to four QSFP56 connections, helping simplify top-of-rack and adjacent-rack layouts. This type of cable is a practical fit for environments that need to preserve bandwidth while keeping power draw and component count under control. By using passive direct attach copper, it avoids the cost and operational overhead of transceiver-based designs for short runs. That makes it a strong choice for tightly packed compute, storage, and switching fabrics where every rack unit and every cable path is planned. For teams standardizing on Lenovo networking hardware, this cable supports clean breakout architecture with minimal complexity. It is the kind of interconnect you choose when the design goal is not just speed, but controlled deployment at scale.
